Second Hand Mercedes-Benz 190E Air Flow Meter

Yes, but only on certain engine variants — the 190E models fitted with Bosch KE-Jetronic or L-Jetronic fuel injection use an air flow meter (also called an air mass sensor or airflow sensor) as part of the fuel metering system. Carburettor variants of the 190 series do not use one. Check your V5 or run a VIN check to confirm your engine code before searching for this part.

The Mercedes-Benz W201 190E ran as a single generation from 1982 to 1993, with a facelift in 1988 that brought minor cosmetic and trim updates but no fundamental change to the engine lineup. The engine code is still the single most important detail for air flow meter fitment, as Bosch injection system specifications varied across the 1.8, 2.0, 2.3, and 2.6 engine variants rather than by pre- or post-facelift production date. Always supply your engine code to the breaker rather than relying on the model year alone.

The 1988 facelift was largely cosmetic and did not overhaul the fuel injection systems, so the engine code remains the primary fitment guide across that boundary rather than the facelift year. That said, whether a specific unit from a pre-1988 car crosses cleanly to a post-1988 car — including any ancillary or mounting changes that may have occurred mid-production — is something you should confirm with the breaker against your exact registration and engine code, as we cannot guarantee interchange across that boundary.

For the air flow meter itself, gearbox type is not a primary fitment factor — the unit is part of the fuel injection system and is governed by the engine code and fuel system specification rather than transmission choice. Confirm your engine code with the breaker and they can match the correct Bosch unit to your car.

No — trim level does not affect air flow meter fitment on the 190E, as this is a mechanical fuel system component determined entirely by the engine fitted. The 190E was sold in various specification levels in the UK but those differences were cosmetic or comfort-related; if two cars share the same engine code, the air flow meter application is the same regardless of trim.

Unlike more modern Mercedes-Benz models, the W201 190E uses older Bosch mechanical or early electronic injection without the complex ECU pairing and immobiliser coding found in later vehicles, so this is less of a concern here. However, whether any electronic matching or calibration is required for the specific injection variant on your car is something to confirm with the breaker or a specialist against your registration, as we cannot state this as fact for every unit.
